Question

Solubility is the ability of a material to carry energy.

• A. True
• B. False

Answer 1

The correct option is B

False

Solubility is the maximum quantity of solute that can dissolve in a certain quantity of solvent at a specified temperature.

Observe the table below depicting the solubility of $KCl$ at different temperatures:

$\begin{array}{cccccc}Temperature\to & {10}^{\circ }C& {20}^{\circ }C& {30}^{\circ }C& {40}^{\circ }C& {50}^{\circ }C\\ KClSolubility\left(gper100ml\right)& 31.2& 34.2& 37.2& 40.1& 42.6\end{array}$

For example, at ${20}^{\circ }C$, a maximum of 34.2 g of $KCl$ can be dissolved in 100 mL of water. If more KCl is added, it will remain undissolved.
